After the failed Bay of Pigs invasion in April 1961, Fabio Grobart was one of the most trusted of Fidel’s confidants and government officials. As late as 1986 Grobart was still a very prominent and influential Cuban communist leader, in the third Cuban Party Congress in that year it was Grobart who introduced Casto to the delegates.
Richard Wolf predictably became Castro’s ambassador to Israel in 1960 and successfully promoted trade and scientific exchanges, which allowed Cuba to break the US blockade of the country.
